I am trying desperately to understand some fundamental concepts regarding Bandwidth. I do not have an Engineering degree (although I think it may help at this point), but here is my question:
I am confused when we say that a current travels at the speed of light on copper...how does that relate to bandwidth?? More fundamentally, how does the measurements of bandwidth relate to Windowing? MTU? MSS?
Here is an example and why I get confused:
Computer A and Computer B hooked up with 100mbps Ethernet.
This says I can send 100 million bits in one second. so this is the capacity of the link...but what is the propagation speed for those 100 million bits???
Here is the REAL question I have. If I send a 64K file between two computers, one at 10 mpbs and one at 100 mpbs.....will it get there faster on the 10 mbps link or the 100 mbps link??? I would say it shoud not matter and it will arrive at the same time (given there is no other traffic) because 64K consumes so little of the capacity of this link in either case. So what determines the SPEED at which this 64 K travels???
